In a poll conducted by the General Social Survey, 81% of respondents said that their jobs were sometimes or always stressful. Let X be the number of respondents that said their jobs were sometimes or always stressful. Ten workers are chosen at random Calculate the following probabilities using Rguroo and then fill in the blanks with your answers. Round your answers to three decimal places. a) P (X = 7) = b) Р (X <5): c) P (X > 3) = d) P (X > 8) = e) Calculate the expected number of workers who their jobs were sometimes or always stressful. Round to the next whole number (e.g. 1.01 - 2) Е (X) — п*р —
